Inputs of Portland Cement Concrete Parameters Needed for the Design of New and Rehabilitated Pavements in Mississippi
Record Type: DOT

Mississippi Department of Transportation MDOT is implementing the mechanistic-empirical pavement design methodology developed under NCHRP 1-37A. This pavement design method characterizes the pavement materials by fundamental properties such as modulus and Poisson’s Ratio. For rigid pavement design the Portland Cement Concrete (PCC) is characterized by: (1) modulus of rupture; (2) compressive strength; (3) modulus of elasticity; (4) tensile strength; (5) coefficient of thermal expansion; (6) concrete shrinkage; (7) unit weight; and (8) Poisson’s ratio. In this study PCC mixes encompassing a range of aggregate types with various blends of Type I cement, Class F or C fly ash and slag that are typically encountered in Mississippi will be evaluated for these parameters.
